一个简单的php Calender(日历),解决了2038问题,这样在32位机和64位机上都可以用了，代码很简单，方便修改

注意32位机有2038问题，所以32位服务器的年限范围1970年~2038年

我们还可以使用DateTime来规避这个问题(这样与32位64位无关了)

function myCalender($year = '', $month = '', $timezone = 'Asia/Shanghai')

date\_default\_timezone\_set ( $timezone );

$year = abs ( intval ( $year ) );

$month = abs ( intval ( $month ) );

//是否是32位机

if ($year < 1970 or $year >= 2038)

$year = date ( 'Y' );

$year = date ( 'Y' );

if ($month <= 0 or $month > 12)

$month = date ( 'm' );

//上一年

$pretYear = $year - 1;

使用DateTime 类解决2038问题，这样不分32位与64位，代码如下：

if ($year <= 0)

$year = $nowDate->format( 'Y' );
